[1] The company routinely uses foreign currency exchange contracts to offset its net exposures, by currency, related to the foreign currency-denominated monetary assets and liabilities. The objective of this program is to maintain an approximately balanced position in foreign currencies in order to minimize, on an after-tax basis, the effects of exchange rate changes on net monetary asset positions. The net pre-tax exchange gains and losses are recorded in other (loss) income, net and the related tax impact is recorded in (benefit from) provision for income taxes on continuing operations on the interim Consolidated Income Statements.

[2] Miscellaneous income and expenses, net, generally includes interest items, insurance recoveries, litigation settlements and other items.
